Is creating a new bootloader is necessary?

[zappos23]

Hi,

I am not seeing any blue light when try to use it to active my google account 2 step authentication. I've done compiling the firmware and is loaded in to the device successfully. But it doesn't seems to work.
I saw there is a step to build the open bootloader. Is this step necessary to get this working?

THanks

I ran into the same problem and I could not flash OpenBootloader as it is not signed (error from nRF Connect).
Are you trying to use an nRF52840-MDK from MakerDiary or the nRF52840 dongle from Nordic?

I am using the dongle from Nordic. I came to realized after searching through the web on flashing a new bootloader into the dongle is impossible without hardware intervention. To install new bootloader you need to hardware reset the device.
Fortunately, for this tutorial, you dont need to install a new bootloader to get it working.
If you plan to use this app as your daily 2 pass security, i think you should explore openSK from google instead. Because this app doesnt support FIDO2 thus limited support.

Hi, did you manage to get this working with the nordic dongle? I have been unable to do so, I think it's something to do with the button mapping? Cheers,

Unfortunately no. I've given up :(

Did you get it working with OpenSK? I'm trying to build OpenSK with the --programmer=none option, but it fails when trying to create the Hex files. I know this is off topic, but has anyone got that working? Keen for the Hex files if you have...
